Do not discard the conversion error.

Both calls assign the returned error to _. If optional.Convert_string_To_optional_String ever returns an error, the flavor value is silently dropped. Propagate the error instead.

As per path instructions for **/*.go: "Never ignore error returns".

♻️ Proposed fix

 	case in.FlavorID != nil:
 		var id optional.String
-		_ = optional.Convert_string_To_optional_String(in.FlavorID, &id, s)
+		if err := optional.Convert_string_To_optional_String(in.FlavorID, &id, s); err != nil {

Use simple assignment for GOPROXY.

GOPROXY now uses recursive assignment. Make re-runs go env GOPROXY on every expansion, and the variable is exported, so the subprocess runs for each recipe invocation. Use := to evaluate it once.

-GOPROXY = $(shell go env GOPROXY)

Inline comments:
In @.github/dependabot.yml:
- Around line 108-111: Remove the exact-name ignore entries for
golang.org/x/crypto and golang.org/x/text from both release blocks in the
Dependabot configuration, while preserving the existing wildcard rules that
restrict only major and minor updates.

In `@api/v1beta1/conversion.go`:
- Line 404: Constrain the v1beta1 API fields corresponding to NetworkMTU,
AdditionalPorts, and the Monitor fields with validation Maximum markers matching
the int32 range before conversion. Remove the unsupported gosec suppression in
the conversion logic and ensure these fields cannot reach the narrowing
conversions with out-of-range values.

In `@api/v1beta1/openstackmachinetemplate_types.go`:
- Line 44: Update TestOpenStackMachineTemplateConversion to populate
Status.Conditions on the OpenStackMachineTemplate and assert that conversion
preserves those conditions in both ConvertTo and ConvertFrom; verify only the
relevant condition fields and do not require Severity or ObservedGeneration to
round-trip.

In `@api/v1beta2/types.go`:
- Line 1036: Update the validation marker associated with the subnets field so
it is an active diff line and uses MaxItems rather than MaxLength for the slice
limit; preserve the intended limit value of 2.

In `@CONTRIBUTING.md`:
- Around line 61-65: Update both support matrices: add the v0.15 row to the
first matrix, mark v0.13 as EOL there, and add an empty v1beta2 column cell to
the historical v0.10–v0.12 rows in the second matrix so their existing support
remains under v1beta1.

In `@controllers/openstackfloatingippool_controller.go`:
- Around line 89-91: Update the error handling around patchHelper.Patch in the
reconciliation flow so a patch failure is aggregated with an existing reterr
instead of being discarded. Preserve the current standalone patch-error message
when reterr is nil, and follow the aggregation pattern used by OpenStackCluster
reconciliation for both errors.

In `@controllers/openstackmachine_controller.go`:

official GitHub Dependabot documentation ignore conditions security updates dependabot.yml

💡 Result:

<search_synthesis>
In the GitHub dependabot.yml configuration file, the ignore option allows you to exclude dependencies from Dependabot updates [1]. Understanding how this interacts with security updates is crucial: 1. How Ignore Works: When you define an ignore rule for a dependency (by name, version, or update type), Dependabot applies these filters to its update process [2][3]. If you specify an ignore rule that excludes a dependency entirely (e.g., just providing dependency-name), Dependabot will generally stop proposing both version updates and security updates for that dependency [1][4]. 2. Interaction with Security Updates: - General Ignore Rules: If an ignore rule matches a dependency, it is typically excluded from all updates, including security updates [1][4]. - Update-Types Limitation: The update-types parameter in an ignore rule specifically targets version updates (semver-patch, semver-minor, semver-major) and does not apply to security updates [1]. Official documentation states that security updates are created regardless of the update-types setting [1]. - Granular Control: Because security updates are meant to address vulnerabilities, they often take precedence. If you need to ignore routine version updates while ensuring you still receive security updates, relying solely on dependency-name ignores may be too broad [1][4]. 3. Managing Security Updates: - To disable version updates while keeping security updates active, you can set open-pull-requests-limit: 0 for a package ecosystem [5][6]. Security updates do not count toward this limit and will continue to be generated [5][4]. - You can also manage ignore preferences directly on existing pull requests using the @dependabot ignore command, which allows you to ignore specific updates without necessarily modifying the dependabot.yml file for global settings [1]. For detailed configuration parameters such as dependency-name, versions, and update-types, refer to the official Dependabot options reference [2][3].

That is a different fix: how to keep a capped dependency from blocking Dependabot security updates. Some dependencies are expensive to upgrade. A PyTorch bump can require a new CUDA toolkit and NVIDIA driver, so it gets scheduled rather than merged, and the obvious response is to tell Dependabot to ignore the package. That response also switches off the package’s security pull requests. Dependabot expands an `ignore` entry that names only a dependency into the version range `>= 0` and applies it on the security path as well as the version path. Scoping the rule to version updates fixes it. The examples use PyTorch, because CUDA coupling is the clearest reason to defer an upgrade, but none of the configuration is specific to it. Packages that only need to age rather than be deferred take a cooldown instead, configured alongside the rest of a uv project’s Dependabot setup. ## Prerequisites - A uv project with `uv.lock` committed. - Dependabot security updates enabled on the repository, under Settings → Advanced Security. That setting is what opens security pull requests. `.github/dependabot.yml` can narrow which security updates Dependabot proposes, never enable them. - Dependabot’s uv security updates. ## Scope the ignore rule to version updates Ignore version updates for the torch family, and name the update types explicitly. This is a complete `dependabot.yml`, not a fragment: .github/dependabot.yml ```yaml version: 2 updates: - package-ecosystem: "uv" directory: "/" schedule: interval: "weekly" ignore: - dependency-name: "torch*" update-types: - "version-update:semver-major" - "version-update:semver-minor" - "version-update:semver-patch" ``` Listing all three types blocks every version update, exactly as a bare rule would; what changes is the rule’s scope. Naming the update types fences the rule out of the security path: Dependabot’s own job log marks each one `doesn&`#39`;t apply to security update`, and the options reference documents `update-types` as a filter on version updates, not security updates. The `torch*` glob matches every package whose name starts with `torch`, including `torchvision`, `torchaudio`, `torchmetrics`, and `torch-geometric`. Name `torch` alone to confine the rule to the one package. The CUDA packages torch pulls in do not start with `torch`, so they keep proposing version updates. Add `nvidia-*` and `cuda-toolkit` to the same `ignore` list to cover them. To stop routine pull requests for every package in the ecosystem rather than for one, add `open-pull-requests-limit: 0` beside `schedule:`. Security updates do not count against that limit and keep arriving. Note A security update targets the minimum version that clears every open advisory, not the newest release. On a CUDA-bound package that jump can still cross a toolkit boundary, so treat a torch security PR as a tested upgrade rather than a merge. ## Confirm the rule took effect A rule that parses is not necessarily a rule that applies, and the failure stays silent until a security fix fails to arrive. Open Insights → Dependency graph → Dependabot, click Recent update jobs beside the manifest, then view logs on a security run. A correctly scoped rule names each update type and marks it as not applying: ```console Ignored versions: version-update:semver-major - from dependabot.yml (doesn&`#39`;t apply to security update) version-update:semver-minor - from dependabot.yml (doesn&`#39`;t apply to security update) version-update:semver-patch - from dependabot.yml (doesn&`#39`;t apply to security update) ``` A rule still scoped too broadly logs the expanded range instead, and blocks the ru…[truncated] <title>Configuring Dependabot security updates - GitHub Docs</title> https://docs.github.com/en/code-security/how-tos/secure-your-supply-chain/secure-your-dependencies/configure-security-updates Configuring Dependabot security updates - GitHub Docs # Configuring Dependabot security updates You can use Dependabot security updates or manual pull requests to easily update vulnerable dependencies. ## Who can use this feature? Users with write access Copy as Markdown ## In this article ## Managing Dependabot security updates for your repositories You can enable or disable Dependabot security updates for all qualifying repositories owned by your personal account or organization. For more information, see Managing security and analysis features or Managing security and analysis settings for your organization. You can also enable or disable Dependabot security updates for an individual repository. ### Enabling or disabling Dependabot security updates for an individual repository On GitHub, navigate to the main page of the repository. Under your repository name, click Settings. If you cannot see the "Settings" tab, select the dropdown menu, then click Settings. In the "Security" section of the sidebar, click Advanced Security. To the right of "Dependabot security updates," click Enable to enable the feature or Disable to disable it. For public repositories, the button is disabled if the feature is always enabled. ## Grouping Dependabot security updates into a single pull request In order to use grouped security updates, you must first enable the following features: - Dependency graph. For more information, see Enabling the dependency graph. - Dependabot alerts. For more information, see Configuring Dependabot alerts. - Dependabot security updates. For more information, see Configuring Dependabot security updates. Note When grouped security updates are first enabled, Dependabot will immediately try to create grouped pull requests. You may notice Dependabot closing old pull requests and opening new ones. You can enable grouped pull requests for Dependabot security updates in one, or both, of the following ways. - To group as many available security updates together as possible, across directories and per ecosystem, enable grouping in the "Advanced Security" settings for your repository, or in "Global settings" under Advanced Security for your organization. - For more granular control of grouping, such as grouping by package name, development/production dependencies, SemVer level, or across multiple directories per ecosystem, add configuration options to the`dependabot.yml` configuration file in your repository. Note If you have configured group rules for Dependabot security updates in a`dependabot.yml` file, all available updates will be grouped according to the rules you&`#39`;ve specified. Dependabot will only group across those directories not configured in your`dependabot.yml` if the setting for grouped security updates at the organization or repository level is also enabled. ### Enabling or disabling grouped Dependabot security updates for an individual repository On GitHub, navigate to the main page of the repository. Under your repository name, click Settings. If you cannot see the "Settings" tab, select the dropdown menu, then click Settings. In the "Security" section of the sidebar, click Advanced Security.

Bounds-check NetworkMTU before the narrowing conversion.

NetworkMTU is optional.Int and carries no +kubebuilder:validation:Maximum marker in api/v1beta1/openstackcluster_types.go (Lines 73-78). A value above the int32 range therefore reaches this line and wraps silently, so the hub spec receives a wrong MTU and the round trip returns a different value. The nolint:gosec comment suppresses the warning without establishing the invariant. The same pattern applies to AdditionalPorts (Line 461) and the Monitor fields (Lines 465-468).

The durable fix is a Maximum marker on the v1beta1 fields. If you prefer to keep the guard in the conversion, reject or clamp out-of-range values here.

The subnet-limit marker is inert and uses the wrong rule.

The line has no leading +, so controller-gen ignores it and the generated CRD contains no limit on subnets. MaxLength also applies to strings, not lists; the correct marker for a slice is MaxItems.

Reset Status.Ready before the early-return paths, not after them.

The comment states the goal is to avoid reporting a stale Ready=true. The assignment sits after reconcileFloatingAddressFromPool, getOrCreateServerPorts, and getOrCreateServer. Each of those returns before Line 416.

Consider a server that reached ACTIVE, so Status.Ready is true. The instance is then deleted outside the provider. getOrCreateServer sets InstanceReadyCondition to False with InstanceNotFoundReason and returns at Line 526. Status.Ready stays true. OpenStackServerStatusReportable keys on Status.Ready at Line 857, so dependent controllers keep observing a ready server that no longer exists.

Move the reset to the start of reconcileNormal, after the label initialization, so every failure path clears it.

🐛 Proposed fix

 	labels := openStackServer.GetLabels()
 	if labels == nil {
 		labels = make(map[string]string)
 		openStackServer.SetLabels(labels)
 	}
+
+	// Set to false by default to avoid reporting a stale Ready=true on any
+	// early return below. It is set back to true only for an ACTIVE instance.
+	openStackServer.Status.Ready = false

Then remove the later assignment:

 	openStackServer.Status.InstanceState = &state
-	// set to false by default to avoid reporting stale Ready=true.
-	openStackServer.Status.Ready = false

GHSA-vp52-pcj8-j9qc google.golang.org/grpc affected fixed versions HTTP/2 DATA-frame fragmentation

💡 Result:

<search_synthesis>
The vulnerability identified as GHSA-vp52-pcj8-j9qc affects the google.golang.org/grpc package in Go [1][2]. This vulnerability relates to heap memory exhaustion (Out of Memory) caused by HTTP/2 DATA frame fragmentation [1]. An unauthenticated remote attacker can exploit this by initiating a gRPC stream and sending a payload fragmented into millions of tiny HTTP/2 DATA frames (e.g., 1-byte frames). Even if the total payload remains within configured flow-control windows, the accumulation of these fragmented frames in the recvBuffer creates excessive memory overhead, which can be used to cause a denial-of-service (DoS) via runtime panic or OOM termination [1][2]. Affected Versions: - All versions up to and including 1.83.0 [1][2]. Fixed Version: - 1.83.1 [1][2]. Mitigation and Workaround: - The fix introduces receive buffer compaction, which automatically coalesces consecutive small data buffers into larger ones when overhead is excessive [1][3]. This mechanism is enabled by default in version 1.83.1 [1][2]. - A temporary escape hatch is available via the environment variable GRPC_GO_EXPERIMENTAL_ENABLE_RECEIVE_BUFFER_COMPACTION=false, which can be used to disable this feature if necessary; however, this variable is intended to be removed in a future release [1][2]. This vulnerability is also tracked as CVE-2026-84304 [4][2][3].

Even if the total payload volume falls within the configured connection and stream flow-control windows, each independent fragment incurs memory overhead due to internal tracking structures and queue allocation. Repeated fragmentation massively inflates the heap space consumed by the stream. An attacker multiplexing multiple concurrent streams can exhaust the memory bounds of the runtime, forcing a runtime panic or OutOfMemory condition and leading to a remote Denial of Service (DoS). ### Patches The change to fix this issue is merged in `master` and a patch release, 1.83.1, has been published that contains this fix. ### Workarounds This vulnerability is mitigated by implementing receive buffer compaction. Consecutive small data buffers are automatically coalesced into larger buffers from a shared pool once the overhead is perceived to be excessive relative to actual payload data, drastically minimizing per-frame memory overheads. This behavior is enabled by default. A temporary escape hatch is provided via the environment variable `GRPC_GO_EXPERIMENTAL_ENABLE_RECEIVE_BUFFER_COMPACTION=false` to disable the feature if unforeseen issues arise, but it will be removed in a future release. ### Severity High ### CVE ID No known CVE ### Weaknesses Weakness CWE-400 #### Uncontrolled Resource Consumption The product does not properly control the allocation and maintenance of a limited resource.

🟡 Minor · Rebuild the custom linter when its configuration changes. · Makefile:311-312

311-312: 🎯 Functional Correctness | 🟡 Minor | ⚡ Quick win

Rebuild the custom linter when its configuration changes.

$(GOLANGCI_LINT_KAL) is produced by golangci-lint custom, but its prerequisites do not include hack/tools/.custom-gcl.yaml. After the binary exists, plugin or version changes in that file do not rebuild it, so make lint can run a stale linter. Add the configuration file as a prerequisite.

Proposed fix

-$(GOLANGCI_LINT_KAL): $(GOLANGCI_LINT) $(TOOLS_DIR_DEPS)
+$(GOLANGCI_LINT_KAL): $(GOLANGCI_LINT) $(TOOLS_DIR_DEPS) $(TOOLS_DIR)/.custom-gcl.yaml

The repository context identifies the custom linter configuration at hack/tools/.custom-gcl.yaml.
